Gasoline delivery is part of a group of smaller sources of pollution known as area sources — smaller activities by businesses or facilities that, when measured across a group of sites, can accumulate to large amounts of pollution impacting Delaware’s air quality.
Area Source Compliance Manager
Gasoline vapor emissions are regulated because of their Volatile Organic Compound (VOC) and Hazardous Air Pollutant (HAP) content.
Regulated reactive VOCs are defined in 7 DE Admin. Code, 1101. Gasoline Delivery Vessel VOC vapor emissions are regulated under 7 DE Admin. Code, 1124, Section 27 and controlled through mandatory vapor collection and return to the delivery vessel.
The EPA has identified many HAPs in the complex mixture called gasoline. Primary constituents of concern are: Benzene, Toluene, Ethyl benzene, and Orhtho-, Meta-, and Para-xylenes. These carcinogenic pollutants are regulated under 7 DE Admin. Code, 1124, section 27 and controlled through mandatory vapor collection and return to the delivery vessel.
Those gasoline delivery vessels making a drop (delivery) to any Gasoline Dispensing Facility (GDF) in Delaware are required to apply for and obtain a Gasoline Delivery Vessel permit prior to any delivery. This permit can be applied for online. For permit conditions and additional information please see the permit example.

Note: A Delaware Environmental Application Background Statement must be completed and submitted with permit applications.
Gasoline Delivery Vessels must verify vapor-tightness annually as demonstrated by Method 27 of 40 CFR Part 60 Appendix A.
